Differences in university students’ motivation between a required and an elective physical activity education policy

Objective: The aim of this study was to examine differences in students’ physical activity motivation, competence, and weekly exercise metabolic equivalent units (METs) between universities with different physical activity education (PAE) policy arrangements (ie, a required PAE vs. an elective PAE). Participants: Participants (N?=?953) were purposefully recruited from two universities with different PAE policies 1 week before the start of fall term 2015. Methods: Participants completed questionnaires assessing their physical activity motivation, competence, and weekly exercise METs. Results: The results of this study suggest that having a required PAE policy allows for more students with lower self-determined forms of motivation (ie, amotivation) to be reached in comparison to the elective PAE policy. Conclusions: This finding highlights that a primary value of having a required PAE policy is its ability to reach less motivated students.     

Technology‐Based Communication and the Development of Interpersonal Competencies Within Adolescent Romantic Relationships: A Preliminary Investigation

This study investigated longitudinal associations between adolescents’ technology‐based communication and the development of interpersonal competencies within romantic relationships. A school‐based sample of 487 adolescents (58% girls; M_age = 14.1) participated at two time points, one year apart. Participants reported (1) proportions of daily communication with romantic partners via traditional modes (in person, on the phone) versus technological modes (text messaging, social networking sites) and (2) competence in the romantic relationship skill domains of negative assertion and conflict management. Results of cross‐lagged panel models indicated that adolescents who engaged in greater proportions of technology‐based communication with romantic partners reported lower levels of interpersonal competencies one year later, but not vice versa; associations were particularly strong for boys.     

Developmental Differences in Infants' Attention to Social and Nonsocial Threats

Research has demonstrated that humans detect threatening stimuli more rapidly than nonthreatening stimuli. Although the literature presumes that biases for threat should be normative, present early in development, evident across multiple forms of threat, and stable across individuals, developmental work in this area is limited. Here, we examine the developmental differences in infants' (4‐ to 24‐month‐olds) attention to social (angry faces) and nonsocial (snakes) threats using a new age‐appropriate dot‐probe task. In Experiment 1, infants' first fixations were more often to snakes than to frogs, and they were faster to fixate probes that appeared in place of snakes vs. frogs. There were no significant age differences, suggesting that a perceptual bias for snakes is present early in life and stable across infancy. In Experiment 2, infants fixated probes more quickly after viewing any trials that contained an angry face compared to trials that contained a happy face. Further, there were age‐related changes in infants' responses to face stimuli, with a general increase in looking time to faces before the probe and an increase in latency to fixate the probe after seeing angry faces. Together, this work suggests that different developmental mechanisms may be responsible for attentional biases for social vs. nonsocial threats.     

Outcomes of a revised apprentice carpenter fall prevention training curriculum

Falls from heights are a leading cause of morbidity and mortality among construction workers, especially inexperienced workers and those performing residential construction. This research reports changes in fall prevention behaviors following revision of fall prevention training in a union-based carpenters' apprenticeship program. We used a comprehensive needs assessment to identify gaps in apprentice carpenters' preparation to work at heights, used these results to guide a school-based fall prevention curriculum to fill these gaps, and measured the effects of the revised curriculum on knowledge, beliefs, and fall prevention behaviors.     

The Impact of Family Structure on Utilization of Preventive Care Services among Children under National Health Insurance in Taiwan

This study investigates the role of family structure in children’s access to preventive services in the context of a National Health Insurance (NHI) system. We analyzed the 2005 National Health Interview Survey in Taiwan to evaluate the impact of family structure on the utilization of preventive services, including well-child visits and non-free vaccinations. The extended family and single-father family were found to have a significant impact on care use in the unadjusted model even under NHI. However, after controlling for various health, demographic and socio-economic factors, our findings suggest that family structure does not influence the non-free use of vaccines, and financial constraints, instead, play an important role in making parents decide to have non-free vaccines. To further enhance the health and welfare of the children, our findings suggest that the NHI coverage of children’s vaccines might not be adequate and that non-free vaccines should be provided free to those families who cannot afford them.     

Model-robust supersaturated and partially supersaturated designs

Supersaturated designs are an increasingly popular tool for screening factors in the presence of effect sparsity. The advantage of this class of designs over resolution III factorial designs or Plackett–Burman designs is that n, the number of runs, can be substantially smaller than the number of factors, m. A limitation associated with most supersaturated designs produced thus far is that the capability of these designs for estimating g active effects has not been discussed. In addition to exploring this capability, we develop a new class of model-robust supersaturated designs that, for a given n and m, maximizes the number g   of active effects that can be estimated simultaneously. The capabilities of model-robust supersaturated designs for model discrimination are assessed using a model-discrimination criterion, the subspace angle. Finally, we introduce the class of partially supersaturated designs, intended for use when we require a specific subset of _m1$m_1$ core factors to be estimable, and the sparsity of effects principle applies to the remaining (m-_m1$m-m_1$) factors.     

Reducing situational violence in low-income couples by fostering healthy relationships

This work evaluated a psycho-educational intervention designed to reduce intimate partner violence (IPV) in low-income situationally violent couples. The primary objective was to evaluate the mechanism through which violence was reduced. It was hypothesized that IPV would be reduced via use of therapeutic skills taught during the intervention (i.e., friendship, sex/romance/passion, shared meaning, and conflict management skills). One-hundred-fifteen couples were randomly assigned to a treatment or no-treatment control group. Couples self-reported attitudes reflecting healthy relationship skills and IPV at multiple time points (baseline, post-intervention, and long-term post-intervention). Results support the notion that violence was reduced via an increase in intervention-based skills. Findings suggest that IPV can be safely reduced in low-income situationally violent couples via conjoint treatment focused on building healthy relationship skills.     

Maternal Child Sexual Abuse Is Associated With Lower Maternal Warmth Toward Daughters but Not Sons

Mothers with a history of child sexual abuse report less warmth toward their children, but whether this association differs by child gender is unknown. We examined the association of maternal child sexual abuse and warmth across child gender, accounting for depression, post-traumatic stress disorder, and child physical abuse. We verbally administered self-report measures to a cross-sectional sample of 154 mothers with a child between 8 and 12 years old. Eighty-five mothers based warmth responses on a son, and 69 on a daughter. We conducted a hierarchical multiple regression, including child gender, maternal child sexual abuse, child physical abuse, depression, post-traumatic stress disorder, and 4 two-way interaction terms with child gender. Maternal depression predicted decreased warmth, regardless of child gender, and maternal child sexual abuse predicted decreased warmth, but only toward daughters. Given previous research suggesting that maternal warmth predicts child well-being, the current finding may represent an important avenue of intergenerational transmission of risk in girls.     

The Career Development Quarterly: A 22‐Year Publication Pattern Metastudy

Patterns of articles published in The Career Development Quarterly (CDQ) from 1990 to 2011 were reviewed in this metastudy. Author characteristics (e.g., gender, employment setting, nation of domicile) and article characteristics (e.g., topic, type, design, sample, sample size, participant type, statistical procedures and sophistication) were described and analyzed for trends over time. Significant changes were noted in increased proportions of female authors, international contributors, research articles, more sophisticated research designs, and decreased numbers of practitioner‐authors. These trends highlight a robust journal that continues to evolve to address changing career development and counseling challenges.
